AI Thread Summary
A 5-meter ladder leans against a wall, touching it 4 meters high, with a uniform mass of 10 kg and an 80 kg man standing on the center rung. The discussion focuses on calculating the forces exerted on the ladder by the wall and the ground, emphasizing the need to draw the ladder and identify all acting forces. Participants suggest writing equations for force components in both x and y directions, as well as moments of force about a suitable point. One user calculates the y component as 706.32 N and the x component as 529.74 N, seeking validation of these results. The conversation also touches on the importance of adhering to forum guidelines for clarity and respect.

A 5 metre long ladder in equilibrium leans against a wall, touching it 4 metres above
the ground. The ladder’s mass is uniformly distributed and is equal to 10kg. An 80kg
man stands on the centre rung of the ladder. Assume the wall is frictionless but that
the ground can exert a frictional force. Calculate the forces exerted on the ladder by
the wall and the ground. And does anyone knows any thing about bonding and anti-bonding order in molecular orbitals...

Thanks alot

welcome to pf!

hi smokee! welcome to pf! :wink:

(pleeease don't give two different threads the same title! :redface:)

draw the ladder with all the forces acting on it

write equations for the components of force in the x and y directions, and for the moments of force about some suitable point …

what do you get? :smile:​
 
ere thanks a lot tiny-tim

please i still don't get much about it, see what i did, i found the distance on the ground from the bottom of the wall to the bottom of the ladder, its 3 metres then i calculated the angle at which the ladder is leaning on the wall...its 53.13 degress...

ok, that's the angle

now write equations for the components of force in the x and y directions, and for the moments of force about some suitable point …

what do you get? :smile:​
 
y component is 706.32 N
x component is 529.74 N

@tiny-tim, do u fink dats correct?

thanks a lot for helpin

Stop the silly writing and please read the guidelines.
 
that is a little bit mean, calling my writing silly, you can say that in a more better way and i will still understand you.

Well i will stop :L
 
smokee, I agree with Evo … stop the silly writing and please read the guidelines :redface:

i'll guess it's correct …

but if you want people to check your work, you need to show it …

what do you get? :smile:​
